Pixhawk 2.1 Standard Set & Here+ V2 RTK GNSS Combo

Compatible with ArduCopter, ArduPlane and ArduRover flight control software.

Due to production limits, ships from late May

PixHawk 2.1 main features:

Single board, high performance integrated flight controller

Increased reliability and reduced integration complexity

Improved sensor performance

Best ease-of-use in open-source world

Enough I/O for any application

Improved microcontroller resources

Key design points

All-in-one design with integrated FMU and lots of I/O ports

Designed for easy mounting (no vibration isolation needed)

Separate power supplies for FMU and IO with battery backup

RTC clock

Integration with standard power brick

Voltage, Current and Fault Sensing

Battery voltage and current reported by each of the two supported power bricks can be measured and logged by the FMU. In addition, the 5v unregulated supply rail can be measured, to detect brownouts and abnormal surges.I/O board sensor can measure the servo power rail voltage. Over-current conditions on the peripheral power ports can be detected, and hardware lock-out prevents damage in case of persistent short-circuits on these ports. The lockout can be reset by FMU software.The under/over voltage supervisor for FMU provides an output that is used to hold FMU in reset during brown-out events.

Battery Backup

Both the FMU and IO microcontrollers feature battery-backed real-time clocks and SRAM. The on-board backup battery has sufficient capacity to recovery from unintended power loss or other causes of in-air restarts.
